KB-ASP.NET 1.1發生DLL Access is denied錯誤
這是同事遇到的問題，長久以來，他的個人電腦對他呵護倍至，深怕他寫程式抓Bug太過勞累，每天會有十幾次不定期的強迫休息時間。前一秒鐘還跑得好好的ASP.NET網站，下一秒要用Visual Studio Debug時，便浮出以下的錯誤訊息，此時除了等待或重新開機外，IISRESET也無濟於事。依據經驗，等待時間長短不一，最長可能會持續五分鐘。

由於訊息中出現Access is denied: 'MyUtility'，原本期望用Process Monitor可以快速找出問題，沒想到連半個Access Denied的Log也沒看到。
重新出發，用錯誤訊息的關鍵字找到這篇微軟KB，原來是Indexing Service搞的鬼，在製作索引的過程中會鎖定Temporary ASP.NET目錄一到五分鐘(剛好與經驗中等待時間吻合)，造成ASP.NET程式無法運作。解決方式是停用Indexing Service或將Temporary ASP.NET目錄排除在索引掃瞄範圍之外，今天停用服務後跑了一整天，同事再也沒藉口進行"非自願休息"了。
